Hart Smart Indicators
Description
The HART standard expands the 4-20 mA signal into a modulated, industry-standard digital HART signal. Standardized sets of parameters can be used for cross-vendor operation of all HART devices. HART Device Descriptions (EDD) are used to integrate HART devices in SIMATIC PDM and SIMATIC PDM Maintenance Station, ensuring easy operation and commissioning of field devices even in hard to reach locations.
